At present, in the period of high-speed development in China, equipment for crushing various ores and building sandstone aggregates is in great demand, and the impact crusher is particularly suitable for crushing various medium-hard ores and sandstone aggregates. The plate hammer of the existing impact crusher is of a ship-shaped structure, and is a utility model patent with the application number of 'CN 201120050409.6', the application date of 2011-12-28, the name of 'high-efficiency large crushing cavity impact crusher', and the technical scheme is as follows:
a high-efficiency impact crusher with a large crushing cavity comprises a front impact plate, a rear impact plate, a machine shell and a rotor body. The utility model discloses a rotor block through having "ship type" board hammer has increased broken chamber, has improved the production holding capacity of breaker to a certain extent, but this kind of board hammer crushing efficiency is low, and the building stones need many times broken could reach the standard, and the energy consumption is also higher for the crushing effect of counterattack formula breaker is not good.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving the problem that prior art medium plate hammer crushing efficiency is low, the energy consumption is higher, adopt "dogleg" board hammer, improve the crushing efficiency of board hammer through set up solid protruding structure on the board hammer face, and then improve the crushing effect of breaker when reducing the energy consumption.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
the utility model provides a high-efficient counterattack formula breaker bar hammer, includes hammer block, tup and mount pad, and the tup distributes at the hammer block both ends, and the tup longitudinal section at both ends is type parallelogram, goes up the tup and is parallel with lower tup, and the tup passes through slick and sly with hammer block contour line junction, is distributing solid protruding structure on the bar hammer face.
The longitudinal section of the plate hammer is a centrosymmetric figure.
The mounting seats are positioned on two sides of the hammer body, and the plate hammer is assembled on the rotating wheel assembly through the mounting seats.
The plate hammer and the solid protruding structures on the plate hammer are cast by wear-resistant alloy steel.
The striking surface of the plate hammer is always vertical to the running tangent of the rotating wheel.
The utility model has the advantages that:
(1) the utility model discloses set up solid protruding structure on the face of striking of board hammer, can increase the strike point of former stone when former stone is broken, at the contact point of every protruding structure and former stone, all can form a little broken center, and the reinforcing crushing effect that can be very big is applicable to the occasion that needs highly broken stone material changes.
(2) The utility model discloses the board hammer is the same with runner traffic direction with the runner assembly back, the tup orientation of board hammer for the face of striking of board hammer remains throughout perpendicular with runner operation tangent line, guarantees the crushing effect of impact crusher. When the arc abrasion of one side of the plate hammer is finished, the plate hammer can be installed in a vertically-overturning mode. The method has the advantages of reducing unit crushing power, reducing the running cost of the impact crusher and avoiding safety accidents caused by ore splashing out of the crusher.

FIG. 1 is a schematic longitudinal section of a plate hammer;
FIG. 2 is a schematic view of a half of the striking face of the hammer;
wherein,
1. a hammer head; 2. a hammer body; 3. a mounting seat; 4. a striking surface; 5. and (4) a solid convex structure.
Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Example 1
The utility model provides a high-efficient counterattack formula breaker bar hammer, includes hammer block 2, tup 1 and mount pad 3, and tup 1 distributes at 2 both ends of hammer block, and the 1 longitudinal section of tup at both ends is type parallelogram, goes up the tup and is parallel with lower tup, and tup 1 and 2 contour line junctions of hammer block transition slick and sly, and the solid protruding structure 5 is being distributed on the bar hammer face of attack 4.
From the longitudinal section of the plate hammer, the parallelogram-like structure is shown in the specification, and the connecting part of the sideline of the profile of the longitudinal section of the hammer head is in smooth transition; the hammer head at the upper end of the hammer body is called an upper hammer head, the hammer head at the lower end of the hammer body is called a lower hammer head, and the method is still applicable when the plate hammer is overturned for use; the longitudinal section of the board hammer is connected with the contour line of the hammer body by one or more arc lines; the included angles between the upper hammer head, the lower hammer head and the hammer body are all obtuse angles; the striking surface is divided into a main striking surface and an auxiliary striking surface, the upper surface of the hammer head is the auxiliary striking surface, and the surface where the contour line of the obtuse angle formed between the hammer head and the hammer body is located, namely the surface in contact with the front surface of the sand stone is the main striking surface.
